Select two-dimensional shapes
Key notes:
- A circle is a shape that is completely round. It has no vertices.
A triangle has 3 sides and 3 vertices.
- Sides are the straight lines that make a shape.
- A vertex is where two sides of the shape meet. Vertices is the word for more than one vertex.
A square is a shape with 4 equal sides and 4 right angles.
- Sides are the straight lines that make a shape.
